    • Aluminum doped zinc oxide (AZO) coated optical fiber LMR refractometers—An experimental demonstration 

      Ozcariz Celaya, Aritz Upna; Piña-Azamar, Dafne A.; Ruiz Zamarreño, Carlos Upna; Dominguez, René; Arregui San Martín, Francisco Javier Upna (Elsevier, 2019)   Artículo / Artikulua
      This work presents the experimental demonstration of lossy mode resonance generation by means of aluminum doped zinc oxide thin-films. The use of such material may allow to optimize the performance of LMR-based sensors, ...
    • Electric discharge detection and localization using a distributed optical fiber vibration sensor 

      Costa, Igor Brutkowski Vieira da; Weber, Guilherme Heim; Gomes, Danilo Fernandes; Galvão, José Rodolfo; Silva, Marco J. da; Pipa, Daniel R.; Ozcariz Celaya, Aritz Upna; Ruiz Zamarreño, Carlos Upna; Martelli, Cicero; Silva, Jean Carlos Cardozo da (Elsevier, 2020)   Artículo / Artikulua
      Partial discharges are a type of electric discharge that cause localized breakdowns in a small portion of an insulating material without forming a complete rupture. In high power electric machines as well as in transmission ...
    • Generation of lossy mode resonances with different nanocoatings deposited on coverslips 

      Fuentes Lorenzo, Omar; Goicoechea Fernández, Javier Upna; Corres Sanz, Jesús María Upna; Del Villar, Ignacio Upna; Ozcariz Celaya, Aritz Upna; Matías Maestro, Ignacio Upna (Optical Society of America, 2020)   Artículo / Artikulua  OpenAccess
      The generation of lossy mode resonances (LMRs) with a setup based on lateral incidence of light in coverslips is a simple platform that can be used for sensing. Here the versatility of this platform is proved by studying ...
    • Is there a frontier in sensitivity with lossy mode resonance (LMR) based refractometers? 

      Ozcariz Celaya, Aritz Upna; Ruiz Zamarreño, Carlos Upna; Zubiate Orzanco, Pablo Upna; Arregui San Martín, Francisco Javier Upna (Nature Publishing Group, 2017)   Artículo / Artikulua  OpenAccess
      A tin dioxide thin layer has been studied in order to improve the sensitivity of lossy mode resonances (LMR) based sensors. The effects of the thin film thickness and the polarization of light in a SnO2 coated D-shaped ...
    • Lossy mode resonance optical sensors based on indium-gallium-zinc oxide thin film 

      Ozcariz Celaya, Aritz Upna; Dominik, Magdalena; Smietana, Mateusz; Ruiz Zamarreño, Carlos Upna; Del Villar, Ignacio Upna; Arregui San Martín, Francisco Javier Upna (Elsevier, 2019)   Artículo / Artikulua
      This work discusses an application of electrically conductive and optically transparent indium-gallium-zinc oxide (IGZO) thin films for fabrication of lossy mode resonance (LMR) based optical fiber refractometers. The films ...
    • Micro and nanostructured materials for the development of optical fibre sensors 

      Elosúa Aguado, César Upna; Arregui San Martín, Francisco Javier Upna; Del Villar, Ignacio Upna; Ruiz Zamarreño, Carlos Upna; Corres Sanz, Jesús María Upna; Bariáin Aisa, Cándido Upna; Goicoechea Fernández, Javier Upna; Hernáez Sáenz de Zaitigui, Miguel Upna; Rivero Fuente, Pedro J. Upna; Socorro Leránoz, Abián Bentor Upna; Urrutia Azcona, Aitor Upna; Sánchez Zábal, Pedro Upna; Zubiate Orzanco, Pablo Upna; López Torres, Diego Upna; Acha Morrás, Nerea de Upna; Ascorbe Muruzabal, Joaquín Upna; Ozcariz Celaya, Aritz Upna; Matías Maestro, Ignacio Upna (MDPI, 2017)   Artículo / Artikulua  OpenAccess
      The measurement of chemical and biomedical parameters can take advantage of the features exclusively offered by optical fibre: passive nature, electromagnetic immunity and chemical stability are some of the most relevant ...
